Editor-in-Chief Axel Alonso told Entertainment Weekly that when the idea was presented to put someone new in the Hulk's role, Cho was the obvious choice. "Amadeus came to mind for a lot of different reasons. One of them is that physically, he's like Banner: he's the 98-pound weakling who's had everything but the physical aspect to make him seem super cool," Alonso said in an interview. "And secondarily is that he's so different from Banner. He shares the monstrous intellect but he's so different - he's a teenage kid, who's hasn't lived much yet. When Banner inherited the burden of being the Hulk, he was an adult. And I think that it showed in the way that he responded to it. Amadeus is a plucky kid. He's got a chip on his shoulder, he's the fifth or sixth smartest guy in the world according to the official rankings, and I think he's just going to carry himself very differently with that power."

The reveal should make a lot of sense to readers familiar with Pak's previous Hulk run; Amadeus Cho was created by Greg Pak and artist Takeshi Miyazawa in 2006 for an issue of "Amazing Fantasy" and quickly moved into a supporting role in Pak's "Incredible Hulk" run. Cho remained with the book when the lead character shifted from Bruce Banner's Hulk to Hercules. The young character, the seventh smartest person on Earth, has since served as a member of the Mighty Avengers and recently appeared in Jonathan Hickman's "New Avengers" run as a member of the Illuminati.
